2018 DS DS3 1.6L Diesel · CF18 VTK

The latest MOT test conducted on 2026-03-04 resulted in a mixed outcome, with the vehicle failing due to a major defect in the offside front constant velocity (CV) joint boot, which had split or become insecure, allowing dirt ingress and compromising the joint’s sealing integrity. While this failure is critical, the preceding MOT on the same date recorded only advisories related to worn suspension arm bushes on both sides of the front axle, indicating that the CV joint issue was not previously present. The overall maintenance trend appears to be stable in terms of structural and functional components, aside from the newly identified CV joint failure, which suggests that the vehicle has not been subject to severe mechanical neglect but may require immediate attention to prevent further damage to the drivetrain. The recurring advisories on suspension arm bush wear, while not severe, highlight ongoing friction and potential long-term consequences if not addressed, particularly in terms of alignment and steering system integrity. The recorded mileage of 53,551 miles for a vehicle aged approximately eight years represents a reasonable annual usage rate of around 6,694 miles, which is consistent with typical driving patterns for this model class. This level of mileage does not indicate either excessive wear from high mileage alone or prolonged periods of inactivity, which could otherwise accelerate corrosion or fluid degradation. However, the CV joint failure at 53,551 miles is notable, as CV joints are designed to withstand significant mileage, and their boot failure typically stems from neglect rather than normal wear. The absence of higher mileage spikes in the MOT history suggests that the vehicle has not been subjected to extreme driving conditions or heavy loads, which could have accelerated wear elsewhere. Still, the CV joint’s condition warrants immediate inspection to confirm the extent of internal damage and to replace it promptly, as further deterioration could lead to premature bearing failure or transmission issues. For a prospective buyer, the most critical immediate inspection should focus on the CV joint and its associated boot, ensuring that the joint is fully functional and that no internal components are damaged. During a test drive, listen for unusual noises from the front axle, particularly a grinding or clicking sound when turning sharply, which could indicate a failing joint. Additionally, check for any oil leaks around the CV joint housing, as this may confirm the boot failure. The worn suspension arm bushes, while not failing the MOT, should be addressed to prevent excessive movement in the suspension system, which could lead to misalignment, uneven tyre wear, or steering play. Inspect the front tyres closely, as the recurring advisories on edge wear and sidewall damage suggest that the vehicle may have been driven with misaligned wheels or underloaded, leading to premature tyre degradation. Verify that the tyres are within legal limits and that there are no further signs of damage, such as cracks or bulges. Beyond the immediate concerns, the DS3’s age and mileage make it prudent to conduct a thorough physical inspection for signs of standing corrosion, particularly around the rear axle and underbody, where the advisory noted corrosion but not serious weakening. Check the brake system for signs of corrosion on discs or binding calipers, especially if the vehicle has been stored for extended periods, as this can lead to reduced braking performance. Inspect the exhaust system for leaks or structural damage, ensuring that emissions compliance is maintained, and verify that the engine oil and transmission fluid levels are adequate, as fluid degradation can occur over time even with low mileage. A service history check would be beneficial to confirm that routine maintenance, such as oil changes and filter replacements, has been conducted according to manufacturer recommendations. Finally, given the vehicle’s age, consider a professional inspection of the electrical system, including the 12V battery and wiring harness, to ensure reliability, as older vehicles can develop subtle but critical issues that may not be apparent during an MOT.
